Kinetic controlled release study of salicylate anion from synthesized and characterized of Ni Al-salicylate-layered double hydroxide nanohybrid

الملخص EN

Synthesis of Ni / Al-layered double hydroxides intercalated with Salicylate Anion to obtaining nanohybrid compounds.

The ion exchange method was used with molar ratio Ni / Al = 4.

The resulted material was characterized by Fourier transform infrared spectra (FT-IR), XRD (X-ray diffraction), and the release profiles of the guest anion to hydrogen phosphate and sulphate aqueous media.

The accumulated release in to hydrogen phosphate more than sulphate.

Release kinetics of salicylate anion has been evaluated with various models such as zeroth order, first order and pseudo-second order.

It is observed that the release profiles of salicylate Anion were governed by pseudo second order.
